Vedder was an Imperial Armymajor stationed on the planetRhamalai during the Galactic Civil War. When GeneralYrros noticed that Denel Moonrunner looked familiar, and determined that his father was a former Imperial major named Corvus Langlier, he told Vedder to have Denel brought to his office. Vedder responded that Denel was on assignment, however, and since Denel was still a conscript, Yrros said he could not be allowed to leave the base, and had to be located immediately.
